WASTE AND YENT COCK.

To all whom 'it may concern.

Be it known that I, Jossnu ll. (irL'AUBER, a citizen of the UnitedStates, residing at Cleveland, in the county of (Juyahoga and State ofOhio, have invented certain new and useful improvements in Waste andVent Cocks, and do declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to w'liich'it appertains to make and use the same.

My invention relates to a new and improved construction of waste andvent cock, all substantially as shown and described and particularlypointed out in the claims.

I In the accompanying drawings, Figure 1 is a sectional elevation of theinvention complete and showing the valve closed on the- Fig. 2 is a mainseat and the waste o'pe-n. vertical cross section of the invention atright angles of Fig. l and with the main valve open and the wasteclosed. Fig. 3 is a detail of tho cap er bonnet which contains the wasteand vent openings, and Fig. 4 is a detail of the gasket thcrcfor. Figs.5 and 6 are details res n-Actively of the tubular packs ing and packingholder adapted to be emplo ed as hereinafter fully described.

hese several views show a combined waste and vent cock which is adaptedto brin the waste to any radial point about the )onnet or cup andaccording tothe position the cock may occupy on the pipe,- and theventis so dispose-d or positioned in respect to the waste outlet-as alwaysto bring it on a higher plane than the said outlet,

whichever wa the said outlet is turned, as-

will hereinafter more clearly appear.

Referring to the several parts, A represents the valve casing, B thebonnet or cap thereon, (.1 a coupling nut uniting said parts, D thevalve, E the waste passag- )acking tube, F the packing holder or thim1c, and

G the gasket interposed between cap B and casing A to prevent leakage atthat point. The details in these several parts comprise the usualdiaphragm '2 in casing A having a "main seat 3 for valve D. Said valveconsists of or compriscsra head 4 having a flange 5 about. its base anda seat 6 and extension 6' fixed to the bottom of said head outsideflange 5 and adapted to occupy seat 3 in diaphragm 2 i'clativclyas shownand whcrcb i said seat is directly ()(f-(JhPlOfl .on' top and within.The valve stem cl has a. quick thread 7 engaged in corresponding thread8 Specification of Letters Patent.

in cup B, by which it is rotated in either direction at will and thevalve is opened or (dosed as to seat 3 or the'waste seat as the case maybe. The waste valve seat likc wise occupied by valve 1) involves a:holder or thimblc l seated in the to of neck 10 of the casing and apacking tulic .lC seated in said holder. it will be noticed ihatholdcr lis a loose and separate incinhcr,jhaving a narrow flange 9 about itsouter edge ada ited to rest in acorresponding recess in neck A) as wellas to fit snugly-within the smooth side of said neck. 'lhus, said necksup aorts said holder which extends downward therefrom and has'auinwardly extending seat 11 for the packing'tube E. Said packing tube ismade of rubber or lead or composition and is straight inside, and is ofa size in cross section internally to receive and pack head 4 of thevalve. Said head is about the same length as said packing tube andoperates to initially close the waste passa eway through said tubebefore the valve opens at its bottom to pressure side of the water atseat 3, as well as serving to keep said passage closed while the valve.is being carried back to its seat 3. In either case, whether opening orclosing the waste, it is desirable to cut off pressure from theavatersource as quickly possible so that the waste will not be open to saidpressure atany time, and it depends largely on the devices employedbetween the main valve and-the said waste outlet to accomplish this uose; Hence valve head 4 is of the lengtli silibwn and adapted to closein pa'ckin E befdre lower valve extension 6 is with rawn from within sat 3. Then as the valve is raised to when 0 ear seat 3, the water "willbe free to flow t rough the casing and the waste will be entirelyclosed. This latter effect is 0b. tained primarily and quite effectuallythrough valve head 4, but the seal is made. perfect v flange 5engagingpacking ring 12 and both seatin thereon and. compressing packingtube tilghtly about head 4 and within thereto to insure venting of thebody of the cock when the waste is opened and thereby promote drainingof the waste water therefrom, no matter what position the cock may bein, either on its side or reversely from that shown. Although. the wasteopening is designated by 18 and the 'vcntopening by 20, it

will be understood that the opening which is uppermost becomes" the ventand the other the waste, all may be determined by the position of thecock. (lap B is also independently mt-atable in respect to the body ofthe cock tlu-reby permitting the waste and vent openings to be properlylocated. for varying conditions. I

Valve stem 61 is packed usual at the top of cap B, coupling nut (.lunites body A and cap B, and gasket (i intervenes these parts. Thus, theentire device is made separable and available for repairs.-

A separate packing ring 12 is shown as resting beneath packing tubeE andthis ring is made of suitable material such as fiber or metal to takethe wear and rotary friction of valve flange 5 during its'upward travelto compress packing-tube E within its confining Walls. Ring 12 willalways retain its shape and size even after long usage and make initialclosing of the .main waste passage certain and effective and thisfeature is important when considering I he combination of said ring andpacking tube E. Thus it will be understood that tube E of a compressibleand expansible nature likely to alter in size after repeatedcompressions and frictional wear and when so changed, especially as toits inner diameter, it would not serve as a perfect initial seal. Butcombined with ring 12 initial closure is'alway r certain and then.

the scaling is made doubly sure and abso lutely tight by compressingtube E. The

' value offthis combination of parts is further augmented by the use ofa holder F because both ring 12 and packing tube E require a support andbacking to guide them in {hi-i movements and to conlinc them within 11..limits, either under compression or at r( and to hold them permanentlyso that the removal thereof from the body of the-cock may be easilyaccomplished before or after their use. The use of instantaneous hotwater heaters and extreme hot water conditions now prevailing in manywater line systems has created an. nnperative call for cil'eeti'vepacking means and. replaceable packing, and

the construction of the parts must be such that any suitable packing maybe used as may be found convenient and at hand. Therefore, a holder Eremovable and replaceable within the cock, and packing removable andreplaceable within the holder meets such conditions mostadvantageously.-

' In Fig. 5 I show a rubber or equivalent compressible and expansiblepacking tube E with a single ring or follower 12 beneath adapted to forma seat for the valve, and in Fig. 6 I show several. packing rings Ercmovcd from holder F and said rings may be all of the same material orof different mate- 'matter to make necessary alterations or re rials,such as lead for one and composition of cloth and rubber for another.The advan tage of a tubular packing and holder therefor arranged andconstructed as shown, is that primarily it will have a long life andwill make a perfect seal about valve head 4 under varying'comlitions,and secondly because a new packing or a change from one kind to anothermay be easily and quickly efiected as the same may be removed andreplaced. in a holder separate from the cock. Said cock when on the pipemay be in an out of the way place and difficult to reach but with aremovable holder for the packing it is an easy pairs.
